I do not allude to such smaller points as the oligarchical tendencies of a horse-breeding country and the democratic influence of the proximity of the sea (important though they are for the consideration of Greek history), but rather to those wider views in the seventh book of his POLITICS, where he attributes the happy union in the Greek character of intellectual attainments with the spirit of progress to the temperate climate they enjoyed, and points out how the extreme cold of the north dulls the mental faculties of its inhabitants and renders them incapable of social organisation or extended empire; while to the enervating heat of eastern countries was due that want of spirit and bravery which then, as now, was the characteristic of the population in that quarter of the globe.

Thucydides has shown the causal connection between political revolutions and the fertility of the soil, but goes a step farther and points out the psychological influences on a people's character exercised by the various extremes of climate - in both cases the first appearance of a most valuable form of historical criticism.

To the development of Dialectic, as to God, intervals of time are of no account. From Plato and Aristotle we pass direct to Polybius.

The progress of thought from the philosopher of the Academe to the Arcadian historian may be best illustrated by a comparison of the method by which each of the three writers, whom I have selected as the highest expression of the rationalism of his respective age, attained to his ideal state: for the latter conception may be in a measure regarded as representing the most spiritual principle which they could discern in history.

Now, Plato created his on A PRIORI principles; Aristotle formed his by an analysis of existing constitutions; Polybius found his realised for him in the actual world of fact. Aristotle criticised the deductive speculations of Plato by means of inductive negative instances, but Polybius will not take the 'Cloud City' of the REPUBLIC into account at all. He compares it to an athlete who has never run on 'Constitution Hill,' to a statue so beautiful that it is entirely removed from the ordinary conditions of humanity, and consequently from the canons of criticism.

The Roman state had attained in his eyes, by means of the mutual counteraction of three opposing forces, (7) that stable equilibrium in politics which was the ideal of all the theoretical writers of antiquity. And in connection with this point it will be convenient to notice here how much truth there is contained in the accusation often brought against the ancients that they knew nothing of the idea of Progress, for the meaning of many of their speculations will be hidden from us if we do not try and comprehend first what their aim was, and secondly why it was so.

Now, like all wide generalities, this statement is at least inaccurate. The prayer of Plato's ideal City - [Greek text which cannot be reproduced], might be written as a text over the door of the last Temple to Humanity raised by the disciples of Fourier and Saint-Simon, but it is certainly true that their ideal principle was order and permanence, not indefinite progress.
